Freqtrade: Plotting: Indicators should be defined in Strategy

[Axel-CH]

I think we should have plot indicators details defined directly in Strategy file. That way the user can define more specific plot configuration for each strategy.

Features:

• Dynamic Row / Subplot number
• User defined indicators color
• Possibility to show Strategy related indicators on upcoming plotting web ui #1505

Below the variable proposition:

# Optional plot informations
plot_rows = [
    'main_plot':[
        {'name': 'ema10', 'color': 'red'}
    ],
    'sub_plots':[
        [
            {'name': 'macd', 'color': 'blue'},
            {'name': 'macdsignal', 'color': 'red'}
        ],
        [
            {'name': 'rsi', 'color': 'orange'}
        ],
    ]
]

as long as it's kept optional (so strategies not defining this will still work also for the UI) I guess that's fine, even though it'll clutter the strategy quite a bit for huge strategies.

I would keep color optional since the color is not that important.
maybe consider a "type" section - defaulting to Line but allowing to specify histograms or so ... ? (not sure if that makes sense, but i'm thinking about MACD histogram ...)

you could also use dataframe.columns coming out of populate_indicators to create a list of possible indicators users can select in the UI if this is not defined?

And once selected it generates this list ... so users can copy/paste it to the Strategy? (i know, i'm lazy) ...

I'm agree with you about:

• This parameter should be optionnal
• Color is optional
• Add type, default to line

However for the automatic generation of those parameter from the UI, I don't see a suffisent gain versus time allowed to develop that feature.

The added value of being able to choose indicators in the UI is to make a quick visual observation.
I see two limitations factor here:

• the availables indicators should be already present in dataframe, defined in Stategy
• It's really difficult to use dash for theese kind of dynamic plot edition (should reload entire plot at each indicators modification). More details here: https://dash.plot.ly/faqs

i said "you could" - this makes it a "would be nice to have ..."
one can dream ... no? :smile:
